第三部分阅读理解（共20小题；每小题 2 分，满分 40分）
第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A、B、C﹑D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
For people who want to travel but have never done it before, tour groups provide a good first step for people. Not everyone is comfortable with just picking up and traveling to strange places. Tours can reduce the stress and anxiety that comes with your first trip and make people more willing to travel. New travelers don’t really know what to do when they go to travel. They might not know how to book tours or hotels or speak another language. Tour groups can help do all the work so travelers don’t get stressed.
Secondly you can get your entire package at cheap cost. When bulk（大批）booking is done, the airline as well as hotel offers considerable reduction in fares. This reduction is passed on to you by your tour operator. Sometimes tour operators offer great discounts for large groups. If you book 10 people, you can get a free ticket or two. This will help in bringing down your ticket fare.
As a student it is fun to travel with friends to the mountains or beach. Student concessions（优惠）can help you in getting low cost tickets. Whether it is an educational tour or adventure tour you can always get reduction in rates.
Additionally, a lot of women are uncomfortable traveling alone. They are afraid they are more likely to get hurt, or in trouble on the road. While many women travel around the world by themselves each year, not all women are ready to do so. Tour groups allow single female travelers a group to travel with if her friends don’t want to go travel with her.
Tour groups are great options for travelers. Not everyone is comfortable traveling by themselves. They might also need a bit more comfort. But that doesn’t mean they have to be excluded（排除）from traveling. Tour groups give people the chance to travel without moving too far out of their comfort zone at first. They are great for first time travelers looking to spread their wings a bit.

It is Saturday afternoon. You and your friends are planning to go to the movies and then spend the night together. Just as you start to get ready, your dad reminds you it is your aunt's birthday and the whole family is going out to dinner to celebrate. How can this possibly end without a huge argument?
One of the greatest sources of tension(紧张情绪)between teenagers and their families is the struggle to balance personal desires with family expectations. As you are getting older，you are becoming more independent and more interested in being with your friends．
However, at the same time，your family is trying to figure out how to deal with these changes．While you once spent most of your free time with your family，you are now often absent from home．Parents may get their feelings hurt. Or they might feel that they are losing control of their family during this period．You might feel angry that so many family demands are placed on you．
There are a few things you can try to make it a little easier to ease the tension．
* Make your plans in advance．Ask your parents if there is anything else planned at that time．
* When something with your friends interferes(干扰；冲突)with a family event，try to figure out if there is any way you can do both．
* Suggest something you would really like to do with your family. Sometimes parents feel better just knowing their teenager wants to spend time with them．
Some of the time you won’t be happy with the outcome. Y ou might either have to disappoint your parents or have to miss out being with your friends．However，if you show consideration for the feelings of both your family and your friends，you can solve the problem in a tender way．

People feel differently about advertising. People who are against it often argue that it is immoral. They say ads are full of tricks. They also contain mistakes in grammar. They argue advertisers will do just about anything to sell their products. Other people say advertisers have a right to speak freely. This is guaranteed by law. They point out that people do not have to view the ads.
Weasel Words
Advertisers often use special words or phrases. These words or phrases are often misleading. These words are called “weasel words.” Advertisers are free to use them as long as they stick to the rules. The government decides what these rules are. Examples of weasel words are “helps”, “virtual”, “new and impr oved”, and “like.”
“Helps”
People often think “help” means stop. Advertisers use it so that they can say things that aren’t necessarily true. Legally, help means to aid or assist. For example, a product can “help” cure indigestion（消化不良）. In fact, the produ ct doesn’t cure indigestion. Can you think of some ads that use “help?”
“Virtually”
To advisers, “virtually” means “not really” or “not in fact.” If you see an ad that says this cold medicine relieves virtually all symptoms, the ad could really mean it doe sn’t relieve any symptoms. Can you think of some ads that use “virtually?”
“New and Improved”
A product can only be considered new for six months. Any small change in a product will make it new. Often, this change does not make a product better. Y et, the change often makes it more expensive. New is often used with “improved.” Can you think of some ads that use “new” and “improved?”
“Like”
“Like”can mean “not in fact.” Some products claim they work “like magic.” Like often takes the audience’s attention off the product. Think of “like magic.” If things are like magic, they are not magic.
Can you think of some ads that use “like” or “like magic?”
64．What can we learn from Paragraph 1?
A．Most advertisements are not reliable.
B．Advertisers use tricks to cheat customers.
C．Advertisements are full of grammar mistakes.
D．People have different opinions about advertising.
65．Advertisers are fond of using “weasel words”.
A．so that they might mislead consumers B．so they are able to show their wisdom
C．because the government allow them to D．because they have the freedom of speech 66．By using the word “help”, advertisers intend to .
A．mean what they say B．show they are honest
C．tell the consumer the truth D．trick consumers trust their products
D
How often one hears children wishing they were grown-ups and old people wishing they were young again．Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets．
Childhood is a time when there are few responsibilities to make life difficult．If a child has good parents, he is fed, looked after and loved, whatever he may do．It is impossible that he will ever again in his life be given so much without having to do anything in return．In addition, life is always presenting new things to the child —things that have lost their interest for older people because they are too well-known．But a child has his parents．He is not so free to do what he wishes to do; he is continually being told not to do things or being punished for what he has done wrong．
When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably．If he spends most of his time playing about in the way that he used to as a child, he will go hungry．And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison．If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society．
67．According to the second paragraph, the writer thinks that __．
A．life for a child is comparatively（比较地）easy
B．a child is always loved whatever he does
C．if much is given to a child, he must do something in return
D．only children are interested in life
68．After a child grows up, he _______________．
A．will have little time playing
B．has to be successful in finding a job
C．can still ask for help in time of trouble
D．should be able to take care of himself
69．The underlined word "responsibilities" in the second paragraph means__________．
A．duties B．jobs C．suggestions D．desires
70．The main idea of the passage is _________ ．
A．life is not enjoyable since each age has some pains
B．young men can have the greatest happiness if they work hard
C．childhood is the most enjoyable time in one's life
D．one is the happiest if he can make good use of each age in his life
第二节（共5小题；每小题2分，满分10分）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Most of us lead a busy life. 71 We think, “If I reached my goal, then I would be happy”, or “If I could get a better job, then I would enjoy life.” But why not enjoy life right now?
Firstly, take time to notice and appreciate the beauty in your own surroundings. 72
“There is a great big world of wonder and beauty around us!” And as Brodersen explains. “Look for the beauty of the sunrise and of a friend’s smile that brightens your day. Open your eyes to see the beauty you might not normally see. Doing so helps to cheer you up.”
Secondly, taking time to experience some simple pleasures also can bring joy to your heart and ease your stress. Take me for example. 73 One universal simple pleasure is finding things that make you laugh. Make time to laugh every day.
Thirdly, don’t take your family and friends for granted. Rich, rewarding relationships add greatly to the enjoyment of life. When you think of someone, why not call, e-mail or write them?
74 As Wayne Lawton explains, “Invest time in relationships. Remove the attitude, what’s in it for me? Happiness is found in putting other’s interests, desires and concerns ahead of our own whenever possible. Selfishness is a dead-end street.”75
A．I delight in simple things like my favorite tea drink, a bubble bath or family photos.
B．In my spare time, I enjoy collecting stamps and reading novels.
C．Driven by the “urgent”, we forget to enjoy life.
D．So please treasure relationship.
E．Y ou don’t need to travel far to find beauty.
F．Be aware of beauty in nature.
G．A short e-mail or phone call can make a world of difference to someone.

One more word, with computers we can get more information and get more knowledge. Don’t you agree?

阅读下列短文，从每题所给的四个选项中（A、B、C和D）中，选出最佳选项。
A
I never knew how amazing it would feel to help a family 4,560 miles away from my home. I never knew how great an effect I could have on that single family.
From the moment I walked into French class, I knew almost instantly that I belonged there. My teacher, Madame Weiser, is a kind and caring woman, and is the person who started the interest within me to help a family abroad, no matter how many miles apart.
Back in 2011, my teacher traveled as a tourist to Maxi, a country settled in West Africa with a large French-speaking population. She didn’t expect to adopt an entire family, but fate had other plans. Madame met a nice man named Monsieur Diarra, a driver who had shown her the way through the dry lands of Mali.
Mali is now a war-torn country and unsafe for tourists to visit, leaving little work for taxi drivers. Madame Weiser realized how Monsieur Driarra’s family struggled on a daily basis, for he had a wife and four children to support as well as their grandmother, so she made a final decision to send the family as much money as she could raise every month.
Now, three years later, Madame Weiser has still kept up her fund, collecting money from family
donating to her adopted family abroad.
As president of French Club at my high school and a French Honor Society member, I decided that our club should work to raise money for the family in need. By washing cars, we raised over $1,000.
From my experience, I’ve learned that making an effort is worth more than anything. Its effect is priceless!
21. Why do taxi drivers have difficulty finding work in Mali?
A. People don’t like taking a taxi.
B. Tourists visiting Mali are few.
C. Mali is very unsafe for them.
D. Public transport is enough.
22. What does the underlined expression “the cause” refer to?
A. Teaching Trench in West Africa.
B. Looking for jobs for the drivers in Mali.
C. Helping the homeless as much as possible.
D. Donating money to the adopted family abroad.
23. What did the writer think of her experience?
A. Boring
B. Puzzling
C. Satisfying.
D. Relaxing.
24. What is the best title of this passage?
A. The Love for Africa.
B. A ind Foreign Driver.
C. My Helpful Teacher
D. My Unforgettable Class

Researchers recently found that hackers took control of 300,000 home routers(路由器). Once your home router has been controlled, hackers could redirect your network to malicious websites controlled by hi-tech thieves who could then steal your online back details and other sensitive data. However, there are some simple steps you can take to protect your router.
Say no to 12345 passwords
First, never leave your router open without a password and make sure you change both your Wi-Fi and router login password from the default one it comes with. If you use the default password , this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys.
Don't broadcast it
Make sure you don't show up in other people's wireless network scans. now your network name so you can easily enter it into any devices you want to access that network. Other people do not need to know your network name. To prevent outsiders from seeing your network's name and attempting to join your wireless network, turn off broadcasting in your router's settings.
Invite only please
One way you can ensure no one else joins your network without your permission is to enable your router to only allow certain devices to connect, and ban all others. To do that you can filter by media access control (MAC) addresses.
Turn it off
This is a simple piece of advice that can go a very long way in keeping you safe. Simply turn off your router when you're not using your network. If you're at work all day and no one's home, why keep it running?
Build a firewall
The firewall built into your router prevents hackers on the internet from getting access to your PC so it's always worth enabling it to help add an extra layer of security. However, it does nothing to stop people in range of your Wi-Fi signal from getting onto your network – and as said, a router in the wrong place means your Wi-Fi signal could reach pretty far.
For further protection, you should run software firewalls on the individual PCs on your networks.
25. If you use the default password, ______________.
A. your home router will be linked to some bad websites.
B. you will find it’s very convenient to surf the Internet
C. your home router will be changed for new settings.
D. you will fail to use your own login password
26. What should be done to shelter your wireless network?
A. To build a firewall into your router.
B. To think out a complicated login password and use it.
C. To shut off your router when you find it not safe.
D. To switch off broadcasting in your router settings
27. The purpose of the passage is to tell____________.
A. how to keep your Wi-Fi network secure
B. how to deal with your home router efficiently
C. how to locate the hackers on the Internet
D. how to prevent others from joining your network.

One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society” is not on the horizon---it’s already here.
While computer offer these conveniences to consumers, they have many advantages for sellers
range of records, including who sold what, when and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how far they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customer for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.
Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.
28. From the last sentence of the first paragraph we learn that ___________ .
A. in the future all the Americans will use credit cads
B. credit cards are mainly used in the United States today
C. nowadays many Americans do not pay in cash
D. it is now more convenient to use credit cards than before
29. If computers record which hours are busiest and which employees are the most efficient, what will businessmen do?
A. They will fire some employees and raise the work efficiency.
B. They will arrange for different employees to do different jobs according to their abilities and performance.
C. They will assign more work for the employees to do.
D. They will allow the personnel to do whatever work they want to do.
30. What does the underlined phrase “ring up sales” in paragraph two mean?
A. make an order of goods.
B. record sales on a cash register.
C. call the sales manager.
D. keep track of the goods in stock.
31. What does the passage mainly discuss?
A. Approaches to the commercial use of computers.
B. Advantages of credit cards in business.
C. Significance of automation in commercial enterprises.
D. Conveniences brought about by computers in business.
D
Culture is one of the most challenging elements of the international marketplace. This system of learned behavior patterns characteristic of the members of a given society is constantly shaped by set of dynamic variables language, religion, values and attitudes, manners and customs, aesthetics, technology, education, and social institutions. To cope with this system, an international manager needs both factual and interpretive knowledge of culture. To some extent, the factual knowledge can be learned; its interpretation comes only through experience.
The most complicated problems in dealing with the cultural environment stem from the fact that one cannot learn culture—one has to live it. Two schools of thought exist in the business world on how to deal with cultural diversity. One is that business is business the world around, following the model of Pepsi and McDonald’s. In some cases, globalization is a fact of life; however, cultural differences are still far from converging.
The other school proposes that companies must tailor business approaches to individual cultures. Setting up policies and procedures in each country has been compared to an organ transplant; the critical question centers around acceptance or rejection. The major challenge
or even blindness.
Fortune examined the international performance of a dozen large companies that earn 20 percent or more of their revenue(税收) overseas. The internationally successful companies all share an important quality patience. They have not rushed into situations but rather built their operations carefully by following the most basic business principles. These principles are to know your adversary, know your audience, and know your customer.
32. According to the passage, which of the following is true?
A. All international managers can learn culture.
B. Business diversity is not necessary.
C. Views differ on how to treat culture in business world.
D. Most people do not know foreign culture well.
33. What does the underlined word “myopia” (in para. 3) mean?
A. difference
B. similarity
C. foresight
D. shortsightedness
34. We can infer from the passage that this article is supposed to be most useful for those_______
A. who are interested in researching the topic of cultural diversity
B. who have connections to more than one type of culture.
C. who want to travel abroad.
D. who want to run business on International Sale
35. According to Fortune, successful international companies______________ .
A. earn 20 percent or more of their revenue overseas
B. all have the quality of patience
C. will follow the overseas local cultures
D. adopt the policy of internationalization

重庆巴蜀中学 关于开展校本课程总结表彰及等级评定的通知各位校长、各位老师： 为了调动学校广大教职工积极参与新课程改革，开发校本课程，促进学校办出特色，促进教师专业发展；也为了整理、总结学校开展校本课程建设的成果，不断提高教师、学校实施校本课程建设的能力，经学校研究，决定自2011年起，每年进行一次校本课程建设总结表彰。现将《巴蜀中学校本课程评价方案》（见附一）公布于此，并对校本课程等级申报、评定工作，做如下部署，请各位老师参照执行。 1、凡是参与过高2011级高一（下）选修课程开设（具体课程名称及指导教师姓名，见附三）的教师及课程；凡是参与过高2013级高一（下）选修课程开设（具体课程名称及指导教师姓名，见附四）的教师及课程，因相关资料在学校已有存档，故相关课程教师，可以不再提交资料及填写申报表，学校组织专家组根据学校已有资料进行评审。 2、学校除高2011级、高2013级外，在其他年级开设过选修课的老师，或附 3、附4有遗漏、错误的教师，请将开课的相关材料进行整理，于7月29日以前将纸质材料，课程等级申报表（见附二）交到本部行政楼二楼课改处。或发往bashu_zhang@https://www.doczj.com/doc/de17786738.html,。逾期不予受理申报申请。 重庆巴蜀中学 2011年7月21日
附一： 巴蜀中学校本课程评价方案 （试行） 一、指导思想及评价原则 落实学校教育理念。校本课程开设要符合学校“教育以人为本，校长以教师为本，教师以学生为本”的教育理念，发现和发展学生的潜能，促进学生全面发展和个性成长，引领教师多元发展。 贯穿学校德育主线。校本课程必须体现学校的“善为根、雅为骨、志为魂”的育人理念，校本课程评价必须依托“公正诚朴”的校训，提升学生对“善雅志”的感悟，培养紧跟时代主旋律的合格中学生。 彰显区域发展特色。校本课程在“131”校本课程体系内，教师可以选择自己认为合适的任何内容来设计课程，但课程的选择要体现学校的办学特色及学校所在区域的政治、经济、文化、社会等各方面实际情况，体现区域发展特色。 把握时代发展脉搏。校本课程的提出和教学内容设计必须符合时代发展的特征，扎根经济、政治、文化和社会的丰厚土壤，尽量体现经济发展的方向、政治民主法治建设进程、文化发展的趋势和社会发展的热点。总之，校本课程要引领时代发展潮流。 坚持科学发展思路。校本课程是在国家课程基础上的拓展，学生能否实现知识、能力、视野的拓展，能否实现情感、态度、价值观的感悟是评价校本课程实施成效的重要内容。因此，校本课程的开发必须与国家课程相一致，与学生身心特点相适应，与学生的兴趣爱好相一致，帮助学生认识科学规律、接受人文熏陶。 二、评价策略

重庆市巴蜀中学2021届高三（上）一诊模拟卷 语文试卷 一、现代文阅读 （一）论述类文本阅读 阅读下面的文字，完成1-3题。 自古以来，东西方都重视美育对立德树人的作用。古希腊柏拉图曾在《理想国》中提出音乐教育对于培养城邦公民勇敢、节制、正义等美德的重要性。而美育之于数千年中华民族社会发展与文化传承亦功不唐捐。上古时期，中国便已出现诗、乐、舞三位一体的乐教；西周建立起来的礼乐文化制度，则对中国数千年文明产生了极为深远的影响。春秋时期，孔子提出的“兴于诗，立于礼，成于乐”“志于道，据于德，依于仁，游于艺”等思想，更奠定了审美教育特别是艺术教育在中国文化中不可替代的地位。孔子深知艺术审美的力量，虽然“礼”与“德”已由德育内化为一种心理要求，但只有“成于乐”“游于艺”的美育才是最高境界。在此，道德目标通过审美转化，成为自由人性的有机组成而发端内心，让枯燥严肃的理性染上灵动的色彩。孔子的美育思想是后世文以载道的理论基础，也是其精神价值核心所在，被此后的儒家所继承。如战国孟子提出“充实之谓美”；西汉《乐记》提出“乐者，伦理者也”；宋明理学经广泛吸收佛道理论之后，将美育理论本体化、精致化、体系化，提倡洒落自得、浑然至乐的人生风范和人生境界，强调通过“乐”这一自由心境的体验，达到真、善、美及知、情、意的统一等等。 不难看出，中国传统美育不仅传授艺术形式带来的审美情感，而且蕴含深厚浓郁的家国情怀、社会理性与道德精神。事实上，道德和艺术正是中华传统文化两大精神基石，中华人文精神亦由此带有泓邃的审美品格。如钱穆所言：“文学必在道义中，而道义则求其艺术化。中国之人生乐处，即在是矣。岂非中国之文化特质乎！”在中国，艺术与道德的有机结合，涵养出一种人格审美求善的美育文化和美育精神，甚至不妨说，中华传统文化精神的形成方式和渠道就是美育。纵观历代中国社会，无不将生活化、道德化的艺术作为人格培养的基本手段。这种通过审美中介来实现外在规范向内在自觉的转变，迥异于德国哲学家康德对抽象“先验理性”或“道德律令”的绝对服从，而是融合具体情境，一方面在艺术审美中追求人格的道德境界，另一方面又在道德培养中追求人格的艺术境界，最终实现“从心所欲不逾矩”的极致。 随着中西文化交流空前密切，中国美育文化和美育精神开始发生变化，其理论形态呈现出中西交融的面貌，也涌现出不少杰出人物和精彩观点。如王国维的《论教育之宗旨》，首次全面论述了美育在教育体系中的重要地位，初步建立起中国现代美育架构。蔡元培筑基于中国传统文化特质的同时，借鉴康德、席勒美育思想中的有益成分，提出“以美育代宗教”。蔡元培还推动美育列入国民教育计划，让中国现代美育走上理论与实践相结合的道路。朱光潜则拓展了蔡元培的美育理论，以当时美学和心理学研究最新成果为依据，强调美育对个体心灵的解放功能，突出了美育作为创新教育的特征和意义，并将美育落实到人的生命体验之中。刘海粟、丰子恺、林风眠等人的艺术教育便属于这种美育观点的践行。如果说王国维、蔡元培、朱光潜等人的美育思想属于启蒙类型，那么，陶行知、徐悲鸿等人奉行的美育思想则将美育的终极指向定位于社会救亡与民族解放。 （摘编自吴为山《以美育提升人文素养筑微博橙子辅导》）1．（3 分）下列关于原文内容的理解和分析，正确的一项是（） A．古希腊柏拉图认为没有音乐教育就不能培养城邦公民勇敢、节制、正义等美德。 B．文章认为在几千年中华民族社会发展与文化传承中美育作用大，是功不可没的。 C．钱穆认为中国文化的特质就是文学与道义是分离的，又是紧密结合在一起的。

一、八年级数学全等三角形解答题压轴题（难） 1．如图，已知△ABC中，AB＝AC＝20cm，BC＝16cm，点D为AB的中点． （1）如果点P在线段BC上以6cm/s的速度由B点向C点运动，同时点Q在线段CA上由C向A点运动． ①若点Q的运动速度与点P的运动速度相等，经过1秒后，△BPD与△CQP是否全等，请说明理由； ②若点Q的运动速度与点P的运动速度不相等，当点Q的运动速度为多少时，能够使 △BPD与△CQP全等？ （2）若点Q以②中的运动速度从点C出发，点P以原来的运动速度从点B同时出发，都逆时针沿△ABC三边运动，求经过多长时间点P与点Q第一次在△ABC的哪条边上相遇？【答案】（1）①△BPD≌△CQP，理由见解析；②V7.5 Q （厘米/秒）；（2）点P、Q 在AB边上相遇，即经过了80 3 秒，点P与点Q第一次在AB边上相遇． 【解析】 【分析】 （1）①先求出t=1时BP=BQ=6，再求出PC=10=BD，再根据∠B＝∠C证得 △BPD≌△CQP； ②根据V P≠V Q，使△BPD与△CQP全等，所以CQ＝BD＝10，再利用点P的时间即可得到点Q的运动速度； （2）根据V Q＞V P，只能是点Q追上点P，即点Q比点P多走AB+AC的路程，设运动x 秒，即可列出方程15 6220 2 x x，解方程即可得到结果. 【详解】 （1）①因为t＝1（秒）， 所以BP＝CQ＝6（厘米） ∵AB＝20，D为AB中点， ∴BD＝10（厘米） 又∵PC＝BC﹣BP＝16﹣6＝10（厘米）∴PC＝BD ∵AB＝AC， ∴∠B＝∠C， 在△BPD与△CQP中，
BP CQ B C PC BD =?? ∠ =∠??=? , ∴△BPD ≌△CQP （SAS ）， ②因为V P ≠V Q ， 所以BP ≠CQ ， 又因为∠B ＝∠C ， 要使△BPD 与△CQP 全等，只能BP ＝CP ＝8，即△BPD ≌△CPQ ， 故CQ ＝BD ＝10． 所以点P 、Q 的运动时间84 663 BP t （秒）， 此时 107.5 43 Q CQ V t （厘米/秒）． （2）因为V Q ＞V P ，只能是点Q 追上点P ，即点Q 比点P 多走AB +AC 的路程 设经过x 秒后P 与Q 第一次相遇，依题意得15 62202 x x ， 解得x= 803 (秒) 此时P 运动了 80 61603 （厘米） 又因为△ABC 的周长为56厘米，160＝56×2+48， 所以点P 、Q 在AB 边上相遇，即经过了80 3 秒，点P 与点Q 第一次在AB 边上相遇． 【点睛】 此题考查三角形全等的证明，三角形与动点相结合的解题方法，再证明三角形全等时注意顶点的对应关系是证明的关键. 2．（1）问题背景： 如图1，在四边形ABCD 中，AB ＝AD ，∠BAD ＝120°，∠B ＝∠ADC ＝90°，E 、F 分别是BC ，CD 上的点，且∠EAF ＝60°，探究图中线段BE ，EF ，FD 之间的数量关系． 小王同学探究此问题的方法是延长FD 到点G ，使DG ＝BE ，连结AG ，先证明△ABE ≌△ADG ，再证明△AEF ≌△AGF ，可得出结论，他的结论应是 ；
